SPECIFICATION forming part of Letters Patent N o, 358,477, dated March 1, 1887. Application inea January 18,1886. semi No. 188.813. (No model.)

.To all whom it may concern.'

Be it known that I, GEORGE' PorrEEr, of Milwaukee, in the county of Milwaukee, and in the State ofWisconsin,have invented certain new and useful Improvements in Sliding Window-Blinds; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to sliding windowblinds; and it consists in certain peculiarities of construction, as will be hereinafter described with reference to the accompanying drawings, in which- Y Figure 1 represents an inside view of a window-frame, showing the application of my invention; Fig. 2, a vertical section on line m x, Fig. l; Fig. 3, a horizontal section on line y y, Fig. 1 Figs.4, 5, 6, and 7, detail sectional views made on an enlarged scale; and Fig. 8, adetail View of one spring-bolt;

A represents a window-frame having the inner portion of the jambs B B cut away, as shown in Fig. 3.

O C represent the upper and lower sashes of the window retained in their operative position by the usual strips or stops. The cutaway portions of the jambs B B areprovided with vertical grooves, andin these grooves are tenoned strips b, said strips forming guides or f ways for the inside blinds, D D D2. The strips b have their outer edges flush with the line of the jambs that come against the sashes C C', so that said sashes may be readily in` serted or removed without interference. The finishing-strips c, that form the outer guides for the lower blind, D, are not tenoned to the jambs B B', but fastened thereto by screws or othersuitable means,so as to have their outer faces flush with the line of said jambs that come against the sashes C G.

The several blinds may be of any desirable construction; but in thisinstance I haveshown them as composed of side panels, d, and central rolling slats, c. The slats a are suitably fastened to rods E, as illustrated more fully in Fig. et. The lower blind-section, D2, is greater in thickness than the two upper sections, D' D, in order that when the slats thereof are closed the rod E will stand on the top of the bottom rail, j', as shown by dotted lines, Figs.

4r, thereby preventing said slats being opened from the outside, though they can be readily opened on the inside by simply springing the rod out from its seat.

The stiles g of the several blind sections have their outer edges grooved, as shown at h, Figs. 5 and 6, and to each of said grooved stiles is suitably secured the inner ends ofa pair of fiat springs, z', the outer ends of said springs being connected to a short hard-wood strip, G, which partly engages the adjacent stile. The hard-wood strips G are of such length as to permit of ready access being had to the inner ends of the springs t, and these strips come in frictional contact with the cut-away portion of the adjacent window-jamb B to retain the respective blind-sections in the position to which they may be vertically adjusted, while at the same time by this construction such adjustment is easily effected. 'Io the stile g of each blind-section is mortised aspring-bolt, H, and these bolts are respectively adapted to engage a correspondingrecess, k, formed `in the jamb B adjacent to the several sections, this construction being more clearlyillustrated in Figs. 7 and 8. l

The spring-bolts by their engagement with the recesses in the j amb B serve to automatically lock the respective blind-sections in place when drawn down to their fullest extent, each section being locked independent of the others in the series, and when all these sections are drawn down they together form a continuous blind, and the bolts H, engaging with corresponding recessesin the j amb B,securely fasten said blind, so that the same cannot be opened from the outside.

rIhe upper central portion ofthe windowcasing is concealed by a panel, I, andthe blindi section D is provided at its top with a hori zontal Hange, m, which forms a bearing for the upper extremities of the sections D D2,so that the entire blind may be pushed up behind the panel when desired, thereby leaving no obstruction to the free entrance of` light. One

or two of the blind-sections may be put out of sight, as above described, without interfering with the others in the series.

By the construction above described it will be seen that the blind-sections can be variously adjusted so as to admit or exclude light from either top, middle, or bottom of the window,

or the blinds can be so adjusted as to wholly admit or entirely exclude the light. Vhen the blindseotio-ns are in their closed position, light or air can be admitted through the slats @,operated by the rods E, the slats in eaehseetion being adjusted independent of those in the others of said sections.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A window-frame having its janibs partially cut away, and provided .with a concealing-panel, in combination with a series of vertical strips designed to be secured to the cut- 4away portions of the jambs, and a series of blind-sections independently adjustable in ways formed by said strips, as set forth.

2.' A window-frame provided with a eoncealing-panel, in combination with a series of verticallyadjustable blind-sections, and the upper one of said sections constructed with a iange forming a bearing, as set forth.

3. A window-frame having the inner portion of its jambs eut away, and vertical strips tenoned in said eut-away portions, in combination with a series of sliding blind-sections independently adjustable iu ways formed by the vertical strips, and each having one of its stiles grooved upon the outer edge and provided with a spring bearing-strip arranged to 3o come in contact with the adjaeentjamb, as set forth.

4, A window-frame having a series of independently-adjustable blind-sections, and the lower one of these sections provided with roll- 35 ing slats and a seat for the operating-rod of said slats when the latter are in their closed position, as set forth.

5. A window-frame provided with a series of independentlyadjustable blind -seetions, 4o each having one of its stiles provided with a groove, in combination with a retaining meehanisni consisting of a pair of flat springs having their inner ends secured to the grooved portion ofthe stile, and a hard-Wood strip se- 45 cured to the outer ends of said springs and arranged to come in contact with the adjacent 1' jamb, as set forth. s1,

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in 5o the county of Milwaukee and State of Wiscousin, in the presence of two witnesses.

GEORGE POPPERT.
